The Importance of the Generations of Isaac

Brooklyn Torah Gazette | December 31, 2025

From the Teachings of the Lubavitcher Rebbe Rabbi Menachem Mendel Schneerson, Zt”l

In this week's Torah portion, Toldot, we read of the birth of Esau and Jacob, Esau's sale of his birthright to Jacob and the subsequent blessing of Jacob and Esau by Isaac.
Jewish teachings explain that the name of a particular Torah portion gives us a special insight into that portion. The name of the portion, Toldot, is derived from its opening words: "And these are the generations (toldot) of Isaac." An earlier Torah portion, Noach (Noah), begins with a similar verse, "These are the generations of Noah."
What is the essential difference between these two portions, as reflected in the Torah's choice of names?
The portion of Toldot emphasizes the concept of descendants. "And these are the generations of Isaac, the son of Abraham: Abraham begot Isaac."

Toldot, related to the Hebrew word for birth (holada), implies both physical offspring and spiritual heirs. When we help a fellow Jew by teaching him about the beauty and warmth of Judaism, we create new "generations," new spiritual children. Even if we are not well-versed in Torah knowledge or the practice of mitzvot, whatever we do know we should share with others. Every Jew has the obligation to act as a "candle" unto his surroundings, spreading the light and warmth of Torah to more and more Jews.
The "generations" we create, however, must be "the generations of Isaac"; it is not enough that we produce "the generations of Noah."
To explain: The name Noah is related to the word n'yacha, meaning rest and repose. Noah is symbolic of a person who is tranquil. It is a desirable state, but one that is less elevated than the level implied by the name Isaac.

The Importance of Laughter and Delight

Isaac (Yitzchak in Hebrew) is related to the word meaning laughter. Isaac is thus a symbol of the joyful person, one who is filled with laughter and delight. Enjoyment is obviously a more desirable state than relaxation, for the person is not only at rest but is happy.
This, then, is the way in which we are to fulfill our mission as "candles that illuminate": It isn't enough for a Jew to quietly share the light of Torah and mitzvot throughout the world in a sedate and easy-going manner. Rather, as we learn from the Torah portion of Toldot, our efforts to inspire our fellow Jews in particular and be a "light unto the nations" in general must be carried out with joy and happiness, as alluded to by the name Isaac.

And the man became rich, and gained more and more, until he became very wealthy (Gen. 26:13)
It often happens that the richer a person gets, the smaller his essential "humanity" and regard for his fellow man becomes. Isaac, however, not only retained his quality of being a "man" the wealthier he grew, but continued his rise to perfection as an empathetic human being. (Rabbi Yitzchak of Torchiv)

Behold, I heard your father speak to Esau your brother (Gen. 27:6)
